Optimizacija procesa izdelave slepe luknje v aluminijastem ulitku

Košir, Rožle (author), Pušavec, Franci (mentor)

V magistrskem delu bomo preverjali različne tehnologije obdelave slepe izvrtine premera 3,63 mm z obojestransko toleranco 0,01 mm. Izmed vseh vplivnih parametrov se bo izločilo tiste, ki imajo dejansko največji vpliv. Osredotočilo se bo na parametre, katerih spremembe predstavljajo najmanjše stroške (orodje, koncentracija emulzije, obdelovalni parametri pri vrtanju). Te parametre se bo poizkušalo optimizirati. Z vsako tehnologijo (kombinacijo različnih parametrov) se bo izdelalo določeno število kosov, ki bodo nato preverjeni z merilno opremo. Tako bomo določili najbolj optimalno tehnologijo za izdelavo slepe luknje v aluminijastem ulitku.

• Title: Optimization of the blind drilled hole into aluminum die casted part

Abstract

In the master's thesis, we will test different technologies for processing a blind hole with a diameter of 3.63 mm with a dual sided tolerance of 0.01 mm. Of all the influential parameters, those with the greatest impact will be excluded. We will focus on the parameters whose adjustments represent the lowest costs (tool, emulsion concentration, processing parameters during drilling). Attempts will be made to optimize these parameters. With each technology (combination of different parameters) a certain number of pieces will be produced, which will then be checked with measuring equipment. Thus, we will define the most optimal technology for making a blind hole in an aluminium casting.
